Well i just passed my 10th month from being with HostingZoom. For those who may be looking for a new host, here's been my experience with them. My site is mcmoser.com (Note that the main page has nothing on it as I use it for the Gallery script)
ZoomPlan: $4.95 / month for 5 Gigs space / 100 Gigs transfer.
Now I would like to mention that I am far from a heavy user. I use this host mainly for pictures and the odd file I need to use elsewhere. I'm currently using 1500 MB of space and in the 10 months i've been with them i've only gone over 1 gig of transfer 3 times (Most was 10.1 Gigs).
I've sent in 2 tickets to support. One was regarding SSH access, which was replied and setup in 15 minutes, and a ticket asking if they had / allowed the FFMpeg plugin, which they did not allow. It was no big deal. That was answered in 9 minutes. Again the few times i used the support, my questions were I suppose fairly basic, but I was impressed by there response time nonetheless.
Well I never saw any downtime, and I do check / use the size a few times a day. If it ever was down, I never noticed. But then again, maybe it never went down :-)
I can upload to my server maxing out my connection at ~105 KB /s. My download speed is usually about 800 KB /s.
They upgraded there DNS servers the other day and I received an advanced warning / email regarding this. Did not notice any downtime, and received an email when they said it was completed. Nice of them to advance the users.
Only thing I could think of, oddly enough, was that I had trouble finding the link to the Billing section. Had to look around and eventually found it under the contact us link. Seems they could maybe improve that.
I myself have had great experience so far with HostingZoom. Hope it continues. For anyone looking to get a new host, they might be someone to consider.
